Android notification badge dot not showing for custom firebase push notification

I have implemented custom view for firebase push notification. For custom view we need to remove "notification" key from push Json so that it can be handled even when app is closed like below:
{
"data": {
"detail": {
}
},
"to": ""
}
For creating custom notification I used below code:
private void generateNotification(String title, String message, Intent intent) {
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
String channelId = getString(R.string.default_notification_channel_id);
PendingIntent pendingIntent = PendingIntent.getActivity(this, notificationCount, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
/*
* Custom notification layout
* */
String notificationHeaderText = getResources().getString(R.string.app_name) + " \u2022 "
+ DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME);
RemoteViews collapsedView = new RemoteViews(getPackageName(), R.layout.view_collapsed_notification);
collapsedView.setTextViewText(R.id.timestamp, notificationHeaderText);
collapsedView.setTextViewText(R.id.content_title, title);
collapsedView.setTextViewText(R.id.content_text, message);
RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.view_expanded_notification);
expandedView.setTextViewText(R.id.timestamp, notificationHeaderText);
expandedView.setTextViewText(R.id.content_title, title);
expandedView.setTextViewText(R.id.notification_message, message);
Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.footer_click);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_inkclick_logo_colored)
.setSound(soundUri)
.setGroup(GROUP_KEY_INKCLICK)
.setAutoCancel(true)
.setGroupSummary(true)
.setCustomContentView(collapsedView)
.setCustomBigContentView(expandedView)
.setContentIntent(pendingIntent);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (manager != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
getResources().getString(R.string.default_notification_channel_id), NotificationManager.IMPORTANCE_HIGH);
channel.enableLights(true);
channel.setLightColor(Color.MAGENTA);
channel.setVibrationPattern(new long[]{0, 1000/*, 500, 1000*/});
channel.enableVibration(true);
channel.setShowBadge(true);
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
channel.setSound(soundUri, audioAttributes);
manager.createNotificationChannel(channel);
}
manager.notify(0, notificationBuilder.build());
}
else {
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (manager != null) {
manager.notify(0, notificationBuilder.build());
}
}
notificationCount += 1;
}
I have added channel.setShowBadge(true); after reading the official notification badge documentation here as well as other answers on stackoverflow like this and this.
I have also tried uninstalling the app and restarting the device but the badge is not showing.
Device is running on API 28(Pie).

You can set style by adding below line
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
add this code
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_inkclick_logo_colored)
.setSound(soundUri)
.setGroup(GROUP_KEY_INKCLICK)
.setAutoCancel(true)
.setGroupSummary(true)
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
.setCustomContentView(collapsedView)
.setCustomBigContentView(expandedView)
.setContentIntent(pendingIntent);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);

You can set the style of the Android notification badge like this:
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
The overall code can look like this:
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_inkclick_logo_colored)
.setSound(soundUri)
.setGroup(GROUP_KEY_INKCLICK)
.setAutoCancel(true)
.setGroupSummary(true)
.setCustomContentView(collapsedView)
.setCustomBigContentView(expandedView)
.setStyle(new NotificationCompat.DecoratedCustomViewStyle())
.setContentIntent(pendingIntent);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);

You need to specify the title or text (setContentTitle or setContentText). Because Android SDK uses it to describe notification in the window which appears when you long-click to the app icon. I don't know why this is not specified in the documentation, but it works this way.

Notification sound is not working in second attempt - Android Studio

I've developed an android app in which i have used opentok videoconference call functionality. I'm getting videocall notification through firebase push notification. But when i'm installing an app first time it is getting sound on notification then when i accept and enters into another activity's videoconference screen after that on next call notification its only vibrate not rings sound.
Below is my notification code snippet:
MyFirebaseMessagingServie.class
private void sendCallNotification(int status, String message, int queryId) {
saveNotificationLog(status, queryId);
long[] vibrate = new long[]{1000, 1000, 1000, 1000, 1000, 1000, 1000, 1000, 1000, 1000};

}
}

}

}

no sound of firebase notifications on marshmallows, but works on oreo

I don't know why when I send a notification to marshmallow, there is no sound, but when I send it to oreo, there is a sound notification.
My firebase code is below
Intent intent = new Intent(this, MainActivity.class);
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.O) {
intent.addFlags(FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("idata", idata);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
} else {
Context c = getApplicationContext();
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
// The id of the channel.
final String CHANNEL_ID = "default";
// The user-visible name of the channel.
final String CHANNEL_NAME = "Default";
NotificationChannel defaultChannel = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
notificationManager.createNotificationChannel(defaultChannel);
intent.setFlags(FLAG_ACTIVITY_NEW_TASK | FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("idata", idata);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
final NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(title)
.setContentText(messageBody)
.setWhen(System.currentTimeMillis())
.setSound(defaultSoundUri)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
.setAutoCancel(true)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setContentIntent(pendingIntent);
notificationManager.notify("myapp", 0, notificationBuilder.build());
}
I searched all over the internet, but there were no results for this, I really needed this, please help me, any help would really be appreciated. thanks

I had the same problem, but the channel id is only used by oreo & higer android versions. If no sound playing in less than oreo, then make sure you have added "sound": "default"//or any custom filename you have in ur res/ folder.
I accidently missed it in my firebase payload.
Addding sound:"default" solved my issue.
Example:
const notificationContent = {
notification: {
icon: "default",
priority:"high",
sound: "default",
android_channel_id: "myChannelID",
title: "new update",
},
data: {//Used on onMessage() function
priority:"high",
android_channel_id: "myChannelID",
click_action: "FLUTTER_NOTIFICATION_CLICK",
title: "new update",
},
};

Android 8 (Oreo) notification not showing up

}
//.setContentIntent(pendingIntent);
NotificationManager notificationManager =

notificationManager.notify(id, notificationBuilder.build());
It used to be working, no clue what's happening on new Android devices like Android O. I didn't try back going to old devices, but it's happening on pixel.

Starting in Android 8.0 (API level 26), all notifications must be
assigned to a channel. For each channel, you can set the visual and
auditory behavior that is applied to all notifications in that
channel. Then, users can change these settings and decide which
notification channels from your app should be intrusive or visible at
all
Notification channels

try this code it works perfectly for me.
Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_CANCEL_CURRENT);
NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
inboxStyle.addLine(message);
NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),"channel_01")
.setSmallIcon(R.mipmap.ic_launcher)
.setContentText(message)
.setContentIntent(resultPendingIntent)
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_HIGH)
.setChannelId("channel_01")
.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
.setStyle(inboxStyle)
.setContentTitle(Title);
mNotificationManager.notify(Notification_ID, mBuilder.build());
NotificationChannel channel = new NotificationChannel(Notification_ID, "Playback Notification", NotificationManager.IMPORTANCE_HIGH);
channel.enableLights(true);
channel.enableVibration(true);
channel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
assert mNotificationManager != null;
mBuilder.setChannelId("channel_01");
mNotificationManager.createNotificationChannel(channel);
}else {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),Notification_ID)
.setSmallIcon(R.mipmap.ic_launcher)
.setContentTitle(Title)
.setContentIntent(resultPendingIntent)
.setContentText(message)
.setStyle(inboxStyle)
.setSound(soundUri)
.setAutoCancel(true);
mNotificationManager.notify(Notification_ID, mBuilder.build());
}

I just figured this one out myself, you need to setup Channels in Oreo, see my previous post on the issue - I though it was a master-detail issue!!! Turns out Oreo has an additional attribute you need but it seems to fail silently if you don't provide it.

Set up notification channels. Example code below
public static void createNotificationChannel(final Context context, final
String channelId, final CharSequence channelName, final String channelDescription, final int importance, final boolean showBadge) {
try {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
postAsyncSafely("createNotificationChannel", new Runnable() {
#Override
public void run() {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
notificationChannel.setDescription(channelDescription);
notificationChannel.setShowBadge(showBadge);
notificationManager.createNotificationChannel(notificationChannel);
Logger.i("Notification channel " + channelName.toString() +
" has been created");
}
});
}
}catch (Throwable t){
Logger.v("Failure creating Notification Channel",t);
}
}

Android notification sound doesn't work

var notificationBuilder = new Notification.Builder(context)
.SetSmallIcon(Resource.Drawable.Icon)
.SetLargeIcon(BitmapFactory.DecodeResource(Application.Context.Resources, Resource.Drawable.Icon))
.SetContentTitle(title)
.SetContentText(message)
.SetAutoCancel(true)
.SetContentIntent(pendingIntent)
.SetStyle(new Notification.BigTextStyle().BigText(message))
.SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetVibrate(new long[] { 1000, 1000 })
.SetDefaults(NotificationDefaults.All);
var notificationManager = (NotificationManager)context.GetSystemService(Context.NotificationService);
notificationManager.Notify(0, notificationBuilder.Build());
Where i was wrong? Why my notifications doesn't have any sound or vibration?

Remove .SetDefaults(NotificationDefaults.All), you are resetting the notification settings that you just built:
var notification = new Notification.Builder(Application.Context)
.SetSmallIcon(Resource.Mipmap.Icon)
.SetLargeIcon(BitmapFactory.DecodeResource(Application.Context.Resources, Resource.Mipmap.Icon))
.SetContentTitle("Stack")
.SetContentText("OverFlow")
.SetAutoCancel(true)
//.SetContentIntent(pendingIntent)
.SetStyle(new Notification.BigTextStyle().BigText("OverFlow"))
.SetSound(RingtoneManager.GetDefaultUri(RingtoneType.Notification))
.SetVibrate(new long[] { 1000, 1000 })
.Build();
var notificationManager = (NotificationManager)Application.Context.GetSystemService(Context.NotificationService);
notificationManager.Notify(1, notification);

Try passing uri to setSound in notificationBuilder like this
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
notificationBuilder.setSound(uri);
